10.1 OBIS (Object-Identification-System)
The Object-Identification-System OBIS is described in IEC 62056-61 and is used for
identification of measured values, e.g. electricity, water, gas and heat.
The OBIS-code system is divided into the value groups A to F. The ITZ provides the
groups C to F.
Value range F: Pre-values
Value range E: Tariff
Value range D: Measuring type
Value range C: Type of measuring variable
In the following table the codes used with ITZ are described.
